CVE-2024-1930

No Limit on Number of Open Sessions / Bad Session Close Behaviour

Published May 8, 2024 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed
Description
No Limit on Number of Open Sessions / Bad Session Close Behaviour in dnf5daemon-server before 5.1.17 allows a malicious user to impact Availability via No Limit on Number of Open Sessions.

There is no limit on how many sessions D-Bus clients may create using the `open_session()` D-Bus method. For each session a thread is created in dnf5daemon-server. This spends a couple of hundred megabytes of memory in the process. Further connections will become impossible, likely because no more threads can be spawned by the D-Bus service.
